Developing table tennis rackets using local materials is crucial to support national sports innovation and athlete performance. This study aimed to evaluate the usability and performance of the Garuda Unesa Speed (GUS) table tennis racket developed using Makassar ebony wood veneer. The evaluation focused on three main aspects: design, functional purpose, and safety. A total of 37 respondents consisting of non-elite athletes, elite athletes, and table tennis experts participated in the trial. A comparative experimental method was used, and data were analyzed using one-way ANOVA and Tukey HSD post hoc tests. Results showed significant differences in design perception (F = 13.275, p < 0.001) and functional purpose (F = 8.642, p = 0.001), but no significant differences were found in safety aspects (F = 2.182, p = 0.128). Elite athletes consistently gave lower scores than the other groups. The GUS racket was well received by both general and expert users, particularly for its balance of design and ease of use. Although elite athletes exhibit higher performance demands, the racket meets basic usability standards and has potential for further development in a professional context. This study is unique in integrating local wood materials with a user-driven evaluation approach in racket development. Its contribution lies in demonstrating that natural material innovations can be validated for high-performance sports equipment, and supporting the advancement of sports technology research.

Background. Physical activity among elementary school children plays a fundamental role in supporting metabolic health, learning readiness, and long-term psychological well-being. The widespread occurrence of sedentary lifestyles, combined with insufficient adherence to recommended physical activity levels, suggests that interventions should extend beyond structured programs and consider students’ psychological preparedness. Objectives. The present study aimed to examine how self-regulation and self-efficacy function as mediating factors linking achievement goals with students’ participation in scheduled physical activity at the elementary level. Materials and Methods. This quantitative study involved 240 fourth- to sixth-grade students from public elementary schools in Surabaya City, aged 10-12 years. Data were collected using closed-ended questionnaires measuring achievement goals, self-regulation, self-efficacy, and scheduled time for physical activity. Partial Least Squares Structural Equation Modeling (PLS-SEM) was applied for data analysis, utilizing the SmartPLS 4.0 software. Results. The analysis revealed that all achievement goal dimensions had significant effects on self-regulation and self-efficacy. Self-efficacy demonstrated a strong positive influence on scheduled time for physical activity, whereas self-regulation showed a significant negative effect. The findings indicate that each dimension of achievement goals influences participation in scheduled physical activity indirectly by way of self-regulation and self-efficacy. The research model substantially explained the variance in scheduled time for physical activity and demonstrated adequate predictive relevance. Conclusions. The findings confirm that strengthening self-belief more strongly determines the sustainability of scheduled physical activity among elementary school students than overly strict behavioral regulation. These results support the development of physical education interventions focused on achieving goals and enhancing self-efficacy to foster sustainable physical activity habits from the elementary school years.

Based upon the validation results, 18 variations of exercise models were deemed feasible for large-scale trials with an average feasibility percentage of 77%. These outcomes were obtained after minor revisions based on suggestions to increase the intensity and duration of the exercises. However, the models were overall deemed feasible without significant changes. The results showed a substantial difference between the group using the target games-based training model and the group using the conventional training model (p < 0.05). The target games-based training model has proved to be more effective in improving the long service ability of beginner players. Conclusions. According to the findings, it can be concluded that the target games-based long service training model provides significant efficacy in improving the long service skills of beginner players. This model is also considered feasible to be applied more widely in coaching beginner badminton players.

Physical ability is an important component in athlete performance, which includes aspects such as strength, speed, agility, and aerobic endurance (VO2max). In the context of futsal, the low understanding and measurement of physical abilities among Liga Nusantara female athletes may hinder the development of their potential. This study aims to measure and analyse the physical abilities of Liga Nusantara female futsal athletes, as well as explore the relationship between these physical variables. The method used was quantitative with a descriptive correlational design, involving 16 athletes taken with a total sampling technique. The instruments used include physical tests which are processed by descriptive analysis. The results showed that the physical condition of the Nusantara League female futsal athletes was generally adequate, there were variations in the ability of strength, speed, agility, and aerobic endurance. The average strength test shows good results, but some athletes are still below average, especially in sit-ups and back-ups. Speed and agility also needed to be improved in some athletes whose results were lower than others, although in general the speed performance was quite good. Aerobic endurance, measured through VO2max, showed good capacity, but inter-athlete differences indicated the need for more intensive cardio training for some individuals. It was concluded that physical ability varies between athletes, with some athletes having strength and endurance that need to be improved. Thus, this study provides valuable insights for designing more effective training programmes to improve the performance of female futsal athletes.

Petanque, as a sport, requires proficiency in shooting techniques and pointing kinematic movements. Understanding the distinctions between these two skills is crucial for novice athletes to excel in the sport. This study aimed to assess the kinematic motion of children practicing petanque pointing and shooting techniques. Employing a quantitative approach with a comparative design, the study utilized purposive sampling to select 21 male novice petanque athletes. Kinematic analysis using Kinovea Software 0.9.4 was conducted to observe throwing success in the sagittal plane. The kinematic data collected for both pointing and shooting techniques were categorized into four stages: backswing, zero position, release, and advanced throwing position. Results indicated significant differences in the backswing phase, particularly in shoulder extension and ball height (α < 0.05). Several variables differed significantly between the two techniques across various phases. Shooting exhibited higher speed (10.94 ± 13.34 m/s) compared to pointing (5.290 ± 0.44 m/s). At the release stage, variables such as ball height, speed, and release angle differed significantly (α < 0.05), with pointing generally resulting in higher ball height (92.53 ± 9.69 m) but slower speed (6.46 ± 0.43 m/s) compared to shooting (80.19 ± 10.74 m and 16.09 ± 5.18 m/s, respectively). Moreover, pointing involved a wider release angle (42.38 ± 5.85 o) compared to shooting (35.31 ± 7.26 o). Significant differences in body and knee flexion, maximum ball height, and ball speed were observed during the follow-through phase (α < 0.05). Notably, ball speed during pointing was slower (4.90 ± 2.35 m/s) than shooting (13.01 ± 5.36 m/s). The study suggests that specific techniques in shooting and pointing can be tailored to enhance training methods for children, thereby improving their performance outcomes. Deep comprehension of the disparities between these techniques enables novice athletes to develop their skills effectively in petanque. Further research exploring various age groups and genders could provide additional insights into petanque throwing techniques.
